Patent CA-2098847-A1 (CA)
Title: Detecting ciguatoxin in serum using stick enzyme immunoassay
Inventor: HOKAMA YOSHITSUGI
IPC: C12Q1/28
Filed: 1991-12-06
Abstract: The present invention relates to a method for detecting the presence of ciguatoxin or related polyether marine toxin in human serum. The steps for detecting the ciguatoxin comprise isolating a serum sample, attaching and fixing the ciguatoxin to a support, and rinsing the resultant toxin-support complex in a buffer to remove unbound toxin and to remove any residual fixer. The presence of ciguatoxin is detected by binding anti-toxin, an antibody against the ciguatoxin conjugated to an enzyme, to the toxin-support complex to form a toxin-antitoxin-enzyme complex. The enzyme of the toxin-anti-toxin-enzyme complex is assayed, and the amount of product formed by the enzyme is then quantitated. A kit for conducting the assay is also described.

Abstract: ABSTRACT        DATA TRANSMISSION SYSTEM AND INTERFACE MODULE AND    PRIORITY GENERATION MEANS INCLUDED THEREIN The interface module. e.g. LIM1, includes a priority generation module PG which determines a priority value PR1 of the module on the basis of which the module competes for access to a common data bus DB and this each time access to that the bus is granted via a grant signal transmitted over a priority bus AB. The priority value PR1 is also transmitted over AB and is determined dynamically based on at least one characteristic of the packet. e.g. on the age of the oldest byte of data packets waiting for transmission in the interface module and/or on the type of information contained in the packet.       Two embodiments of PG are described, one based on a software program and one based on the counter value, at the receipt of the grant signal, of counters associated with each queued packet.

Title: Method and apparatus for eliminating signal sidelobes for a received signal frame in a multichannel receiver
Inventor: THOMPSON JAMES P
IPC: H04B1/40
Filed: 1994-04-07
Abstract: A method and apparatus for use with a multichannel receiver to eliminate signal sidelobes within a received signal time frame is disclosed.  The elimination of signal sidelobes within a channelized receiver is accomplished by using an analog preprocessor.  The analog preprocessor is capable of producing an amplitude mask based upon the determination of the greatest amplitude and frequency channel in a two-dimensional receiver system or frequency channel and time slot in a three-dimensional receiver system signal.  The amplitude mask covers a predefined space in time and frequency equal to or below the peak signal amplitude.  A signal in the frequency/time cell space covered by the mask must have a magnitude exceeding the magnitude of the amplitude mask in order for the signal to pass through the analog preprocessor for further processing.

Abstract: A method of analyzing the performance of a plurality of investments provides both portfolios and benchmarks and enables a user to choose the structure of each, as well as the structure of an attribution model linking them. One or more portfolios are defined, and for each, a class scheme is defined having a variety of nodes, each of which represents an asset class. The nodes can have subsidiary nodes as desired. Each investment is assigned to a respective asset class. At least one market index, which may be a composite of known indexes, is established for monitoring the performance of the investments. A benchmark is defined including at least one market index and including a plurality of separate nodes, each representative of investments of a known type. Again any node structure can be defined and it need not correspond exactly to the node structure of the class scheme. An attribution model is set up linking desired nodes of the class scheme with nodes of the benchmark, whereby the performance of individual asset classes of the portfolio can be analyzed.

Abstract: I devised a concept and then a propulsion engine where by rotating and circulating liquid mercury at high speed inside a special con-tainer, a much greater force can be countered by it then its weight therefore by applying electromagnetically activated jolts or pushes perpendicular to it, the force of the said mercury can give a fix point or a support point to said jolts or pushes, therefore when mounted inside of a flight craft, the flight of the craft can be realized, propulsed from within. The energy needed is electricity and with the eventual use of fusion technology to generate the said electricity the fuel storage problems of long range operations are solved and longtime acceleration can be maintained to realize very high speeds. The guidance possibilitys are above all the presently existing crafts combined. This is a new step in the evolution of flight machines and the possible realisation of a new breed of flight machines with respect to sizes and shapes and controlled flight is possible in both airspace or space.
